Abstract
A battery test unit for testing batteries while stored in a cassette-type package having an electrically conductive base sheet and a housing, mounted on the base sheet, forming a plurality of individual battery compartments. Each compartment stores an individual battery and has a contact access opening in its cover. The housing and the base sheet are arranged to store each battery with one terminal in electrical contact with the base sheet and the other terminal accessible through the contact access opening in the cover of each compartment. The battery test unit of this invention is a handheld, manually operated device comprising a body having a receptacle region for receiving the cassette-type package, a selector switch for selectively individually making electrical connection through the cassette access openings with one terminal of each stored battery in the corresponding cassette compartments, a meter for testing each battery selectively connected by the selector switch, and a main contact for making electrical connection with the cassette base sheet.
